perf hists: Consolidate histsadd_*entry()

2013-11-04T23:59:09Z

The __hists__add_{branch,mem}_entry() does almost the same thing that __hists__add_entry() does. Consolidate them into one.

perf report: Use parse_options_usage() for -s option failure

2013-11-04T15:55:17Z

The -s (--sort) option was processed after normal option parsing so that it cannot call the parse_options_usage() automatically. Currently it calls usage_with_options() which shows entire help messages for event option. Fix it by showing just -s options. $ perf report -s help Error: Unknown --sort key: `help' usage: perf report [] -s, --sort sort by key(s): pid, comm, dso, symbol, ...

perf report: Postpone setting up browser after parsing options

2013-11-04T15:54:32Z

If setup_browser() called earlier than option parsing, the actual error message can be discarded during the terminal reset. So move it after setup_sorting() checks whether the sort keys are valid.

perf tools: Stop using 'self' in some more places

2013-10-23T12:55:37Z

As suggested by tglx, 'self' should be replaced by something that is more useful.

perf report: Add --max-stack option to limit callchain stack scan

2013-10-21T20:36:25Z

When callgraph data was included in the perf data file, it may take a long time to scan all those data and merge them together especially if the stored callchains are long and the perf data file itself is large, like a Gbyte or so. The callchain stack is currently limited to PERF_MAX_STACK_DEPTH (127). This is a large value. Usually the callgraph data that developers are most interested in are the first few levels, the rests are usually not looked at. This patch adds a new --max-stack option to perf-report to limit the depth of callchain stack data to look at to reduce the time it takes for perf-report to finish its processing. It trades the presence of trailing stack information with faster speed. The following table shows the elapsed time of doing perf-report on a perf.data file of size 985,531,828 bytes. --max_stack Elapsed Time Output data size ----------- ------------ ---------------- not set 88.0s 124,422,651 64 87.5s 116,303,213 32 87.2s 112,023,804 16 86.6s 94,326,380 8 59.9s 33,697,248 4 40.7s 10,116,637 -g none 27.1s 2,555,810 Signed-off-by: Waiman Long Acked-by: David Ahern Cc: Adrian Hunter Cc: Aswin Chandramouleeswaran Cc: David Ahern Cc: Ingo Molnar Cc: Jiri Olsa Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Scott J Norton Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1382107129-2010-4-git-send-email-Waiman.Long@hp.com Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add data object to handle perf data file

2013-10-21T20:33:24Z

This patch is adding 'struct perf_data_file' object as a placeholder for all attributes regarding perf.data file handling. Changing perf_session__new to take it as an argument. The rest of the functionality will be added later to keep this change simple enough, because all the places using perf_session are changed now.
